Abstract

In the present study, magnesium-strontium titanate (Mg-SrTiO3) composites were prepared using powder metallurgy route. The physical, mechanical, and electrochemical properties of pure Mg were compared with those of Mg-SrTiO3 composites with varying SrTiO3 concentrations (0, 1 and 5 wt%). X-ray diffraction (XRD) results showed the SrTiO3 and Mg peaks in the composites. Scanning electron microscopy (SEM) of the composite revealed the uniform distribution of reinforcement in the Mg matrix. An electrochemical corrosion study showed that the Mg-SrTiO3 composite has more positive ECORR than pure Mg. The lowest corrosion rate was observed in the Mg-1 %SrTiO3 composite. An in vitro biocompatibility and antimicrobial study revealed that Mg-SrTiO3 composites are non-toxic and have mild antibacterial property.
